The students who passed the exam all had their noses up, but the students who had not passed the exam wanted to hit the wall.

"What happened the first time? Why was the safety officer driven out of the car halfway through?"

Zhang Zhao recalled her first exam process:

"first,"

"That's an accident. When I was on the road, the road conditions were very good. I knew that I was driving and caught up with an exam car in front. At that time, I was calm and knew that I had to keep enough distance from it. Then I thought of a way to surpass it. I couldn't always follow behind, right? As a result, when I turned on the light and wanted to overtake from the left, the car in front suddenly changed lanes!"

"A dog suddenly jumped out of the front. I was scared to drive, right? I didn't react any more and stepped on the brakes, and the car turned off... I had a chance, but I didn't ignite the neutral gear..."

Zhang Nan was stunned when he heard this. According to Zhang Zhao's description, this was a very dangerous driving. She was just a novice. She did not turn the direction randomly, nor did she hit the accelerator, but stepped on the brake to stop the car steadily. She performed very well.

What is it to fire even if the car is turned off and there is no gap? What is it to fail the exam?

"Although you put it lightly, you performed well, and although there were flaws, you have made great progress. Compared to your past, you have made great progress."

You should know that when Zhang Zhao first came to practice driving, he was hitting the wind and rushing around. Zhang Nan felt very pleased and asked her:

"Let's go, let's celebrate what you want to eat."

"I don't have time. I really have to rush back to Nanhai City at noon. The company has received the case. Let's celebrate again when I come back next week to take the subject four o'clock." Zhang Zhao explained.

Zhang Nan immediately raised his left hand and looked at it, "It's still early, it's only 9:30 now, you're on the 12:09 car... Ahem, let's go back to the hotel to celebrate."

This trouble lasted for more than two hours...

At noon, after seeing Zhang Zhao off, Zhang Nan returned to the training ground.

The sun is very poisonous and hot, but it does not affect the students' enthusiasm for driving. Those who practice driving practice driving and those who play cards, Huang Cuiping first discovered that Zhang Nan was back.

“Yo,”

"The coach is back,"

"Why is the car with 0909 clearly turned on the air conditioner, but why is the wind hot?"

"Hmm? I can't go and see," Zhang Nan quickly walked to the 0909 coach car. At this time, Liu Xi was sweating profusely. The water formed by sweat and the foundation on his pretty face fell all the way to the tip of his chin.

But even so, Liu Xi still looked serious and turned the car backwards. Are you really not afraid of heat?

"you,"

"Get out of the car quickly."

"Is it comfortable to steam a sauna on this hot day?"

Zhang Nan felt distressed when he looked at the person and quickly drove Liu Xi out of the car.

After Liu Xi got off the car, he took a look while driving.

paralysis,

I was shocked.

The water temperature meter has been reminding that the water temperature is too high. On the left side of the dashboard, the water temperature has already reached the top!

If you come back later, the car will catch fire.

He quickly turned off the car and hung up the neutral gear. Then he called Liu Yuexun and a few boys to come over, pushed the car into a cool place, and opened the engine hood and let the car cool there.

When he returned to the rest shed, he spoke.

"Why, the car is so hot, don't you call me? Everyone has to steam it in the car. If I come back later, everyone can eat pork head meat."

"Hahahaha! Pig head, senior sister's pork head." There was a burst of laughter in the crowd.

Zhang Nan glared at him, "You can still laugh? Then the time will be roasted pork."

"Does the car have to wait until it catches fire before it gets fun? The temperature is too high, which may cause the car to catch fire at any time, which is quite serious!"

"Liu Xi, your subject 1 is 100 points. There was a red pattern flashing on the dashboard on the car just now. Didn't you notice it?"

Zhang Nan called Liu Xi's name.

Liu Xi replied while wiping the sweat from his forehead.

"I didn't pay attention,"

"I often hear the sound of 'ding ding ding'. Every time I think the handbrake is not put to the end, so I always look at the handbrake, and the handbrake is fine. I think it's a seat belt that is not worn, but there is no one."

"you!"

"It's useless to learn 100 minutes."

Zhang Nan almost died of anger, and he called Huang Cuiping's name again.

"Huang Cuiping, you were the first to find the problem. Have you noticed that pattern?"

Huang Cuiping's neck shrank and immediately buried her head, "Coach..."

"It seems like the reminder pattern of excessive water temperature..."

She still has her own thinking and judgment.

"But we just took a break for twenty minutes, and then the pattern disappeared again. I thought it was okay... Isn't this now..."

"Is this how you deal with problems? Are you lucky?" After hearing Huang Cuiping's answer, Zhang Nan coldly glanced at the students.

"Liu Yuexun, didn't you say you were an assistant teacher? You haven't noticed this problem?"

Liu Yuexun immediately lowered her head in shame.

"I'll tell you,"

"If any prompt appears in the car, you must stop the car and check it immediately to find out the reason. If you can't find the reason, you will find a professional to deal with it or call me to report it. The car will definitely not be able to drive again. The water temperature in the car just now was high, and there are several possible reasons."

"Let's go to the car site to learn more about it." After that, Zhang Nan took the lead and walked to the front of the car of 0909.

While pointing at each device, explaining.

In addition to his students, there were other trainees from the coaching car to watch.

"First, the coolant is insufficient. Look, the cryogen has slipped away from the lowest value, right? At least it means we need to add the cryogen."

"Second, it may be that the cooling fan is malfunctioning. The fan stops turning and does not dissipate heat, and the water temperature will naturally rise."

"The circulating water pump will have problems, the water pump will leak or not circulate."

"There is also a thermostat fault. If the thermostat is broken, it will not be sensed."

"But the refrigerant is obviously too low now. We first need to add refrigerant. If the refrigerant falls back after driving for a while, the water pump will leak. These two reasons may be the temporary reason."

Zhang Nan said so much in one breath, and everyone was listening very carefully.

"Liu Yuexun, you guys, one of you guys will come to get me a bucket of water."

Liu Yuexun and the others quickly went to pick up tap water, and soon three buckets of water were placed in front of Zhang Nan.

"The front of the car has been cold for almost half an hour now. I want to open the lid of the tank now, but you have to remember that if you open it directly, you will be disfigured! Never do this! Because the temperature inside is still very high. Once you open it, the frozen liquid inside will erupt like a volcano, covering your face."

"So, for safety reasons, it will be opened within an hour. If I open it like me, I must cover the lid with a towel and pour it on it with water."

After saying that, Zhang Nan lifted a bucket of water and slowly watered the towel.

"This is to cool down. A bucket of water is not enough. At least four or five pokes are needed. You guys continue to fetch water." He waved his hand and asked Liu Yuexun and the others to run to fetch water again.

After the fifth bucket of water fell on the towel, Zhang Nan called Liu Yuexun over again.

"You continue to water up and slowly now, and I will open the lid."

Zhang Nan finally covered his right hand on the towel and carefully twisted the lid while Liu Yuexun slowly poured water down.

Hissing ~

Silent ~

After several vents of heat emerged from the lid, it became quiet and did not have the volcanic eruption as imagined, which means that the cooling measures just now have achieved results.

"alright,"

"It's all right now."

"The rest is to put the frozen liquid in it."

"How can I say about refrigerant... If it's an emergency, add mineral water, or add refrigerant seriously. Don't hurt the car in order to save more than 100 yuan..."

At this time, the old driver's system finally rang again.

"bite,"

"bite,"

"bite,"
Chapter completed!
